Blend Polyol and Isocynate for the knee protetive pad foam
JYP-A / JYP-B is two component material which is used to make the knee protective pad foam and other soft pad. JYP-A is a blend Polyol which is combined by the polyether Polyol, Polymer polyol and some special slow rebound Polyether Polyol, cross-link agent, foaming agent and composite catalyst etc. JYP-B is isocyaanate MDI which is combined by MDI, modified MDI etc. This kind of material has an excellent liquidity and slow memory result.
